I recently came into posession of this Bulova ladies watch. The inside back cover has the following inscription: Bulova American Standard 14k Goldfilled Pat. June10 1924 8549093. It probably needs a good cleaning otherwise it looks in very good condition. I'm wondering if it's worth servicing or if it might be of interest as a collectors' item. Any information would be appreciated.
The movement model might be SAP -difficult to make out. It is a 15 jewel movement.
Thanks, Bob & Stephen for your input. I'm still unable to find any marks to indicate the date except for something that looks like a three sided symbol (missing a side that would complete a square symbol) to the left of the screw below the winding screw. The additional photo shows more of the other inscriptions - Swiss - Four 4 ADJ. - 52253 - Bulova Watch Co.
Edit Alex: lay-out of movement is 6AP, updated from 5AP
